WASHINGTON -- The Boy Scouts of America and the Girl Scouts of the United States of America are about to throw down.

Here’s why: The Boy Scouts is going to drop the word ‘boy’ from its name in by February 2019 and is now allowing girls to join.

That fact has the Girl Scouts organization miffed and fighting back with a lawsuit.

#2 The Allegations

The GSUSA allege the BSA is infringing on its trademark, making unfair competition, and causing a lot of confusion.

#3 How did we get here?

The Boy Scouts plans to drop the ‘boy’ from it’s name next year to attract more girls to it’s now “all-inclusive” program.

It will now be called Scouts BSA.

#4 BSA’s advertisements are reportedly confusing some people.

The Girl Scouts said BSA’s new name and the way the group is advertising is a problem.

The GSUSA said the Boy Scouts do not have a monopoly over words like “scout” or “scouting” and that advertisements have sparked confusion.

In the complaint, the Girl Scouts said the alleged trademark infringement leads some people to think the groups merged or that the Girl Scouts does not exist anymore.

#5 The lawsuit seeks an injunction against trademark violations and compensation.

Thousands of younger girls have already joined the cub scouts, and the BSA will also be accepting older girls in 2019.

This case is under litigation, and both sides are expected to meet with a judge in January.
